switchlog(8)


NAME

  switchlog - moves an AdvFS file domain transaction log


SYNOPSIS

  /sbin/advfs/switchlog domain_name vol_id


OPERANDS

  domain_name
      Specifies the name of an existing file domain.

  vol_id
      Specifies the number of the new volume to use for the log.


DESCRIPTION

  The switchlog command relocates the transaction log of the specified file
  domain to a different volume in the same file domain.	 Moving the
  transaction log within a multivolume file domain is typically done to place
  the log on either a faster, less congested, or mirrored volume.

  Use the showfdmn(8) command to determine the current location of the
  transaction log. In the showfdmn command display, the letter L displays
  next to the volume that contains the log. The showfdmn command also
  displays all of the volumes and their volume numbers.


RESTRICTIONS

  You must be the root user to use this command.


EXAMPLES

  The following example displays the log's current location by using the
  showfdmn command and then moves it to volume 2 by using the switchlog
  command.

       # /sbin/showfdmn domain_eng
